Pi Network has taken another step toward building its smart contract ecosystem with the release of a new Remote Procedure Call (RPC) server on its Testnet.
The update may sound technical, but its goal is to make it easier for developers to build, test, and connect applications to the Pi blockchain. Unlike earlier stages where users focused on mining coins, the latest move opens the door for actual interaction with the blockchain.
“The Pi Network just rolled out its Testnet RPC Server — and this is more than just a “developer update.” This is the bridge between ideas and real apps,” one analyst said.
What can developers now do?
With the RPC server live on Testnet, developers can start interacting with the Pi blockchain in two main ways:
- Read data instantly (no fees): Developers can check account balances, contract data, or other information without paying fees. These actions don’t change anything on the blockchain and happen almost instantly.
- Make changes (with fees): Actions that update data or run smart contract logic still require normal transaction processing and fees.
The Testnet RPC Server allows developers to directly connect with the blockchain. This means they can read on-chain data instantly without paying fees, execute transactions when required, and test applications before any mainnet release.
This removes earlier limitations where building on Pi was restricted. Now, developers can actively create, test, and refine applications in a working environment, bringing the network closer to real-world usage.
Stronger Base for Smart Contracts
This update builds on the groundwork laid during Pi Day 2026, when the network upgraded to Protocol 20. With the latest move to Protocol 21, support for smart contract functionality is being extended further.
The network is gradually moving from preparation toward actual smart contract interaction, setting up the base for more advanced applications.
Real Development Activity Begins
With direct blockchain access, developers can now build applications that rely on real-time data. They can simulate contract behavior, integrate backend systems, and connect user interfaces more efficiently.
This stage is often where projects begin transitioning from early development into practical use cases, as tools become available for builders.
Expanding Role of Node Operators
Another change is that node operators can now run their own RPC servers. This allows greater participation in maintaining infrastructure and offers flexibility for businesses or developers to manage their own access points.
